WARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
!
A display message is shown if the coolant
temperature is too high.
If the coolant temperature is over 248 ‡
(120 †), do not continue driving. The
engine will otherwise be damaged.
The coolant temperature gage is in the instru-
ment cluster on the right-hand side
(
Y
page 33).
The H marking in the coolant temperature
gauge corresponds to a coolant temperature
of approximately 248 ‡ (120 †).
Under normal operating conditions and at the
correct coolant level, the coolant temperature
gauge may rise to the H marking.
